Natural Window Cleaner And Weed Killer You Can Make At Home

My friend Tracy recently asked, "I'm looking for a natural window cleaner as well as a natural weed killer. Do you have any proven concoctions you would like to share? I'd love to give up the Windex, and pulling weeds around the pool patio -- well, let's just say there must be a better way!" Luckily, there is a better way, and surprisingly, you can use the same key ingredient for both (with some disclaimers).

Natural Window Cleaner

For windows, the classic vinegar and water solution works wonders. I use ¼ cup white vinegar mixed with 2 cups of water in a spray bottle. This simple solution leaves mirrors, glass, and chrome streak-free and sparkling clean. You can easily make a variety of effective household cleaners using common ingredients.

Natural Weed Killer

Weeds are a bit trickier. A study by the University of Wisconsin-Madison Department of Horticulture found that vinegar (acetic acid) is effective as a weed killer, but a stronger 20% solution works best. Most household vinegar is only 5%, making the 20% solution harder to find for regular home use.

However, I’ve successfully used a mixture of vinegar, liquid soap, and water to kill weeds—especially in areas like brick pathways, where you want to avoid harming nearby plants. Be careful with this spray, as it affects most plants it touches. A single application usually kills the plant, though plants with fuzzy leaves seem to be more resistant. For weeds with thick roots, like dandelions, multiple applications may be necessary to fully weaken and eliminate them.

Here’s the formula I use:

  • 1 part dish soap
  • 2 parts vinegar
  • 2 parts water

For a small batch, mix ½ cup dish soap, 1 cup vinegar, and 1 cup water.

It feels great to use simple, natural ingredients that work without resorting to harsh chemicals that are harmful to both you and the environment.

  1. This does sound like an interesting idea. Obviously this sort of thing works better with an area to be weeded. Of course the homemade version would require a long extension cord for the household steamer to reach out into the garden.

  2. Decades ago, I saw a program of a gizmo that killed weeds. It was discovered that if you apply steam to the leaves of a plant and cover it for a period of time (seconds), the steam will destroy the protective coating of the leaves and the plant will die. The gizmo was pulled behind a tractor and was basically a think rubber pad with steam injected underneath. The tractor would drag this steaming pad over a weeded area and then the weeds would die. It would be worth playing around with a piece of visqueen and a household steamer.

    If you are familiar with this or know a better way, I am all ears.
